GOPH ER-EXTERMINATO R.

SPECIFICATION forming part of Letters Patent No. 514,855, dated February 13, 1894. Application filed July 1, 1893. Serial No. 479,378. (No model.)

To all whom it may concern:

Be it known that I, GODFRIEDYLAUBE, a citizen of the United States of America, residing at IIuron,in the county of Beadle and State of South Dakota, have invented certain new and useful Improvements in Gopher-Exterminators, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in exterminators of gophers and other small burrowing animals.

The object of myinvention is to produce a device whereby the smoke or fumes produced by burning sulphur or other matter may be forced into the burrows or holes which shelter the vermin or it can be used with equal advantage in circulating the fumes among plants to destroy insects, &c. In accomplishing the foregoing resultsI have provided the mechanism to be hereinafter fully described and specifically pointed out in the claims.

In describing the invention in detail, reference is had to the accompanying drawings forming a part of this specification, wherein similar reference letters indicate correspond ing parts in the several views, in which- Figure 1:-is a view in front elevation of my device. Fig. 2:is a view in side elevation. Fig. 3:is a vertical sectional view of the same, and Fig. 4:-is a detail view of the valve mechanism. I

In the drawings,-A, indicates the inner cylinder made of sheet, galvanized iron or other suitable material open at the top and having a conical end a, provided with an outlet a This cylinder is designed to retain inflammable material and the fume producing matter; furthermore, it is telescoped by an outer cylinder B, having a longitudinally expansible joint b, held by means of a spring 19*, suitably secured with one arm on either side of said joint that the cylinder may be retained in its normal position and furthermore, adapt itself to inner cylinders of different diameters, effecting close connection thereby, guarding against escape'ment of the fumigated smoke except at the lower opening of the inner cylinder. The handle O, is attached to the inner cylinder to enable the operator to securely retain the exterminator in position while the upper cylinder is being worked by means of the handle D, attached thereto as shown. The top of the outer cylinder is further provided with a valve d,

- been patented showing an inner and outer cylinder. I do not therefore claim broadly such construction.

Having fully described myinvention, What I claim as new, and desire to secure by Letters Patent, is-

1. In a vermin exterminator, the combination of an inner cylinder having a reduced lower portion, the outer cylinder having longitudinally expansible joints and a securing spring, the valve at the top of the'outer cylinder and the shield or guard, substantially as described.

2. In a vermin exterminator, the combination of an inner cylinder as specified, an outer cylinder having longitudinally expansible joint-sand being provided with a valve, a shield over said valve and the handles securedto the inner and outer cylinders, for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
